The sequence of the process:
The surface to be treated is sprayed with the pretreatment product (BMB 1), which has the function of relaxing the surface and opening the pores. The already existing capillary action is intensified. Microcracks are opened and the general permeability is increased. It should be ensured that the deepest possible penetration depth into the material is given by the connection with the following product 2. (This is especially important for algae infestation)
The materials thus pretreated are sprayed several times with the second product (BMB 2). At the pretreatment, the liquid can penetrate through the entire plaster layer and thereby a comprehensive wetting of all microorganisms can be achieved. In addition, this process results in an optical indication of the discolorations. Algae are comprehensively impaired in this process step.
INFO: Many of the current chemical processes (todays standard) work exclusively with thin chlorine solutions. The disadvantages of these methods are the low penetration depths into the material (only superficial effects), the persistence of an aggressive biocide on the topmost plaster layers changes in the pH value too strongly alkaline, the persistence of an aggressive biocide in the material, smell and taste annoyance over longer periods of time. The softeners are removed from the plaster layer by a remaining chlorine-containing / corrosive biocide, thereby destroying them.
After the products BMB 1 in combination with BMB 2 have penetrated into the material and unfolded their effect, it is necessary to remove the products, the microorganisms, organic impurities, other undesired microbiological material (incl Mycelium) and toxic metabolic products from the material. This is achieved by applying BMB 3. Furthermore, the pH value of the plaster layer must be stabilized and led into the neutral range. Immediately with the material contact, several micromechanical reactions take place.
Reaction 1: pH neutralization
Reaction 2: Formation of aqueous hydrochloric acid
Reaction 3: Conversion of the aqueous hydrochloric acid into edible cooking salt
Reaction 4: Pressure buildup and volume increase in the material - harmless mold spores, mycelium, loose organic material / particles, dead algae, dyes, allergens, pollen etc. are pushed through the open pores of the surface completely.
Reaction 5: Slow degradation of the remaining oxygen from the micropores
These first four reactions occur so strongly (foaming) that the completion of the micromechanical reaction can be visually perceived (bioindicator).
When removing algae from insulating facades, the facade has to be washed with water after completion of process step 3, since large organic loads are usually found on the surfaces and may stick to it in case of rapid drying in sunlight.
Phase 4 (optional):
In order to ensure a sustainable stabilization of the treated surface, the surface is treated with a fourth product. Depending on the situation (BMB 4) or (BMB L) is used. BMB 4 / BMB L are easily biodegradable. No bioaccumulation is to be expected. The ingredients do not have persistent, bioaccumulative or toxic properties. The pore openings are reduced in this process step and a balanced situation, protected against algae formation, is created which excludes re-germination in the long term.
After the end of the treatment and the drying and exhalation phase took place, the affected area can be entered and fully used.
In principle, BMB® does not recommend dry nebulization or air treatment in the interior; only in very few cases, in previously highly mold-infested spaces with construction-related very low air exchange (for example in basements or cavities), a final aerosolization step can be performed, if needed.
In an ideal scenario, the interiors are available to the inhabitants again after approx. 2 hours.
